// DecodeBody extracts the configuration within the given body into the given
// value. This value must be a non-nil pointer to either a struct or
// a map, where in the former case the configuration will be decoded using
// struct tags and in the latter case only attributes are allowed and their
// values are decoded into the map.

// The given EvalContext is used to resolve any variables or functions in
// expressions encountered while decoding. This may be nil to require only
// constant values, for simple applications that do not support variables or
// functions.

// The returned diagnostics should be inspected with its HasErrors method to
// determine if the populated value is valid and complete. If error diagnostics
// are returned then the given value may have been partially-populated but
// may still be accessed by a careful caller for static analysis and editor
// integration use-cases.
